The mysterious Palamkota Fort mentioned in Mughal and Maratha records during the late 17th century—has long been a subject of confusion among historians of South Indian warfare. The fort was reportedly besieged by the Mughals after their return from the campaign against the Tanjore Marathas and was connected with Rajaram Chhatrapati, who mortgaged it to King Shahji II of Thanjavur to sustain his forces at Gingee Fort (Jinji) during the Mughal siege. Despite repeated references, no site definitively identified as “Palamkota” survives on modern maps.

Historical Context: The Siege of Gingee
In 1690, following the execution of Sambhaji by the Mughals, Rajaram shifted his base to the fortified heights of Gingee, then one of the most formidable hill forts in India. The Mughals, under Zulfiqar Khan and Daud Khan, laid a prolonged siege that lasted nearly eight years. Gingee remained in Maratha hands largely because of the underground supply lines that connected it with Tanjore and other southern allies.
It is within this logistical network that Palamkota Fort appears—a fortified outpost on the route linking Tanjore and Gingee, used to store or transport provisions smuggled through the Vettavalam woods into Gingee territory. The Mughals’ attempt to storm this position underscores its strategic value: it was more than just a small fort; it was a supply hub sustaining the Maratha resistance.
Reassessing the Geography
The name Palamkota (or Palayankottai in Tamil orthography) has misled many earlier researchers into assuming it refers to the Palayamkottai near Tirunelveli. However, that site lies far to the south—well beyond the reach of the Gingee–Tanjore operations. A more accurate placement would be somewhere between Thanjavur and Gingee, roughly along the historical routes that passed through Vriddhachalam, Tittakudi, and Vettavalam.
When these coordinates are plotted, one fortress stands out both geographically and strategically: Thiyagadurgam Fort in Kallakurichi district. Situated atop rocky hills and controlling the approaches from the south toward Gingee, Thiyagadurgam matches the descriptions of a strong mid-way fort between the two centers of conflict.
Why Thiyagadurgam Fits the Description
Thiyagadurgam’s location makes it a compelling candidate for the Palamkota of the sources:
- It lies on the main supply corridor between Tanjore and Gingee, passing through Vettavalam, where smuggling routes were reportedly active during the Mughal siege.
- The fort stands on granite hillocks, giving it natural defensive advantages that would have warranted a Mughal siege.
- Local traditions and surviving fortifications indicate Maratha-period activity, though later modified under Nayak and British periods.
- The name Palamkota could have been a transcriptional distortion or regional variant used by Persian or Marathi scribes unfamiliar with Tamil toponyms.
Unlike Palayamkottai in Tirunelveli, Thiyagadurgam aligns perfectly with the political geography of the 1690s. It was near the Madurai–Tanjore frontier, within the extended influence of Shahji II, and close enough to Gingee to serve as a staging post.
Archaeological and Cartographic Clues
Although modern maps label Thiyagadurgam clearly, older colonial cartography sometimes used different names or spellings. Some British-era records refer to it simply as “Tiyagadroog” or “Tiyagadurg,” confirming its existence as a notable military site. Today, remnants of granite ramparts, bastions, and watchtowers still dot the hill, though much of the structure lies in ruins.
The fort’s vantage point commands views of the surrounding plains, reinforcing its strategic role as a communication and supply hub during the wars between the Mughals and Marathas. Given its terrain and its position on the ancient Gingee–Vriddhachalam–Tanjore route, Thiyagadurgam fulfills nearly every criterion attributed to the lost Palamkota.
The evidence strongly suggests that Palamkota Fort of the historical records was not the faraway Palayamkottai of Tirunelveli, but rather Thiyagadurgam Fort in present-day Kallakurichi district. Its placement on the vital supply corridor, its hill fort characteristics, and its proximity to the Vettavalam forests—all align with the descriptions preserved in Mughal and Maratha sources.
While definitive archaeological confirmation is still needed, the weight of historical geography and linguistic analysis points decisively to Thiyagadurgam as the true Palamkota—the unsung stronghold that once sustained the Maratha defense of Gingee against the might of the Mughal Empire.
